What [JsonProperty] used for in c#?

Question

For example, why is it needed on below code, how can it further be being used?

public class FileAttachment
{
    [JsonProperty("fileName")]
    public string FileName{ get; set; }
}

In this specific case, it's useless anyway. The default `camelCase` serializer will already serialize to/from `fileName` and not `FileName` — Camilo Terevinto, Jan 29 '18 at 15:39

Per the documentation: this is the json key that will be used when serializing/deserializing this object to/from a json string.

So, if the value of FileName is file.txt, the serialized result would be

{
    "fileName": "file.txt"
}
